Content Providing System Based on Location Information Recognition

1. A user terminal for recognizing a location signal, the user terminal comprising: a first location signal recognizer configured to recognize a first location signal output from a first location signal output device; a second location signal recognizer configured to recognize a second location signal output from a second location signal output device having a coverage smaller than that of the first location signal output device; an access information transmitter configured to transmit access information of the first location signal output device or the second location signal output device to an external service server through a network when the first location signal or the second location signal is received; and a controller configured to make a control to transmit the access information of the first location signal output device to the service server and enable the second location signal recognizer to monitor the second location signal only when the first location signal is recognized.

2. The user terminal of claim 1 , further comprising a third location signal recognizer configured to recognize a third location signal output from a third location signal output device having a coverage smaller than those of the first location signal output device and the second location signal output device, wherein the controller makes a control to transmit the access information of the second location signal output device to the service server and enables the third location signal recognizer to monitor the third location signal when the second location signal is recognized.

3. The user terminal of claim 2 , further comprising a content receiver configured to receive content information determined according to the access information from the service server after access information of one of the first location signal output device, the second location signal output device, and the third location signal output device is transmitted.

4. The user terminal of claim 3 , wherein the controller disables the third location signal recognizer when the third location signal is not recognized after the second location signal and the third location signal are sequentially recognized, and disables the second location signal recognizer when the second location signal is not recognized after the first location signal and the second location signal are sequentially recognized.

5. The user terminal of claim 2 , wherein the first location signal is a geo-fence-based radio signal including at least one of Wi-Fi, GPS, and base station signals, the second location signal is a beacon signal output from a Bluetooth Low Energy (BLE) beacon signal, and the third location signal is a sound wave.

6. A service server for providing content information based on location information of a user terminal, the service server comprising: an access information receiver configured to receive access information of one of a first location signal output device, a second location signal output device, and a third location signal output device from the user terminal, the second location signal output device having a coverage smaller than that of the first location signal output device and the third location signal output device having a coverage smaller than those of the first location signal output device and the second location signal output device; a database unit configured to store a plurality of pieces of content information; a content extractor configured to, when the access information is received, extract at least one piece of content information to be transmitted to the user terminal among content information related to one location signal output device corresponding to the received access information; and a content provider configured to transmit the extracted content information to the user terminal through a network.

7. The service server of claim 6 , wherein the first location signal output device is a device outputting a geo-fence-based radio signal including at least one of Wi-Fi, GPS, and base station signals, the second location signal output device is a beacon device outputting a Bluetooth Low Energy (BLE) beacon signal, and the third location signal output device is a device outputting a sound wave.

8. The service server of claim 7 , wherein the content extractor extracts at least one piece of content information related to a region covered by the first location signal output device when access information of the first location signal output device is received, extracts at least one piece of content information related to a store in which the second location signal output device is located when access information of the second location signal output device is received, and extracts at least one piece of content information related to a product sold in a store in which the third location signal output device is located when access information of the third location signal output device is received.

9. A method of receiving content information based on a location signal by a user terminal, the method comprising: recognizing a first location signal output from a first location signal output device; transmitting access information of the first location signal output device to a service server; enabling a second location signal recognizer for receiving a second location signal output from a second location signal output device, the second location signal output device having a coverage smaller than that of the first location signal output device; recognizing the second location signal; transmitting access information of the second location signal output device to the service server; and receiving content information determined according to the access information from the service server.

10. The method of claim 9 , further comprising: when the second location signal is recognized, enabling a third location signal recognizer for receiving a third location signal output from a third location signal output device, the third location signal output device having a coverage smaller than those of the first location signal output device and the second location signal output device; recognizing the third location signal; and transmitting access information of the third location signal output device to the service server.

11. The method of claim 10 , further comprising disabling the third location signal recognizer when the third location signal is not recognized after the second location signal and the third location signal are sequentially recognized.

12. The method of claim 9 , wherein the first location signal is a geo-fence-based radio signal including at least one of Wi-Fi, GPS, and base station signals, the second location signal is a beacon signal output from a Bluetooth Low Energy (BLE) beacon signal, and the third location signal is a sound wave.
